Attorneys ALBERT HEADLEY, OF TWO HARBOBS, MINNESOTA.

TRUCK-BRAKE.

Application filed March 27, 1915.

To all whom it may concern Be it known that I, ALBERT HEADLEY, a citizen of the United States, residing at Two Harbors, in the county of Lake and State of Minnesota, have invented a new and useful Truck-Brake, of which the following is a specification.

,be conveniently applied to a baggage truck the tongue or handle and and whereby the mechanism is operative in a thoroughly practical and efficient manner for automatically swinging the brake shoes into and out of to cooperate with adjacent wheels,

' engagement with the wheels when the tongue is lowered and raised.- 7

It is also within the. scope of the invention to provide a brake device for trucks which is comparatively simple, non-encumbering and inexpensive in construction, as well as being convenient, practical, serviceable and eiiicient in use. 7

With the foregoingfand other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

. The invention is illustrated in theaccompanying drawing. wherein Figure 1 is a fragmental side elevation of one end portion of a baggage truck illustrating the brake mechanism applied to the steering gear.

mechanism as applied. Fig. 3 is an enlarged sectional detail of the brake beam and accompanying parts, portions being broken away.

in carrying out the invention, there is provided a pair of brackets 1, each of which comprises a horizontal rod'2'and an inclined bar 3. The brackets 1 are adaptedto be carried by the axle andaxle frame of the truck so as to project forwardly. Thus, the rear end portions of the rod 2 are engaged through suitable apertures provided in the axle frame 4, and nuts 5 are threaded upon the rods, 2, to clamp the same to the axle frame 4, while the lower ends of the bars 3 are secured in any suitable manner' to the lower surface of'the axle 6. The bars 3 are each provided with a twist between their ends whereby the opposite end portions of the bars 3 will be disposed in theproper planes- A transverse rod 7 is carried by the forward o-r'free ends of the brackets 1,

the forward or free ends of the rods 2 hav- 7 ing eyes 8 embracing the rod 7, and. the upper or free ends of the bars 3 being aper-. tured and engaging the rod 7 next inside the eyes 8. Nuts 9 are threaded upon the rod 7 for clamping the forward'ends of the respective members or sections 2 and 3 of the two brackets. A transverse brake beam 10,

preferably constructed of channel iron, is p hung from the rod 7 by means of a pair of hangers 11 which have theirlower ends secured to the brake beam 10, and the upper ends of the hangers 11 are engaged to or embrace the rod 7 between the outer nuts 9 and the eyes 8. The brackets 1 thus carrythe suspended brake beam 10, and brake shoes 12 are secured to the ends of the brake beam 10. The web of the beam 10 is disposed forwardly so that theeflanges of the brake beam project rearwardly, and the brake shoes 12 are provided intermediate their ends with forwardly projecting lugs 13 fitting within the ends of the brake beam 10, bolts 1A being secured through the brake shoes 12 and the end portions of the beam 10 for fastening the brake shoes in place. The lugs 13 of the brake shoes fitting within the end portions of the beam 10 will pr vent the shoes from turning. The brake shoes 12 coiiperate with the wheels 15 whichare journaled upon the ends or spindles of the aXle 6. The brackets 1 are-disposed between the wheels 15, and the" rod 7 terminates short of the wheels 15, while the ends of'the brake beam'lO project beyond the innerlsides of the wheels 15 so that the brake shoes 12 will be capable of bearing against "the tires 01?. peripheries of the wheels 15.. The brake beam 10 and its shoes 12 are disposed in front of the wheels.

The brakebeam 10 is braced or reinforced e by means of a truss bar'or strip 16 having its ends clamped betweenthe end portions of the brake beam 10 and the brake shoes '12, atubular truss .17 being disposed between,

the intermediate portion of the trussbar 16 and the intermediate portion of the brake beam 10.' The truss bar 16 lies inirear of the 'brake beam, and the truss 17 projects rearwardly from the saidfbeam, so that the bracing or reinforcing structure will lie in rear of the brake beam between the wheels 1'5. A'bolt'or securing element 18 is engaged through thetruss bar 16, truss l7 and'brake beam 10, and the ends of the truss bar 16 I are engaged bythe bolts 14., The truss structure will resist the rearward pressure given to bear upon the intermediate portion of the brake beam, which tendsto bow or bend the brake beam rearwardly.

Asa means for'operatively connecting the brake beam with the tongue or handle 18 of the truck, a wedge shaped'block 19'is se cunedfby me'ansfof bolts 20 to'the interme diate portion of the brake beam in front of same, so thattheforward face of the block 19 is inclined rearward; i A strip 21 is clamped'against the front face of the block 19 by means of the bolts 20,'and the intermediate portion of the'strip 21 isofiset forwardly, as at 22, to provide a guide through,

' which'the depending arm 23 of an angular V 'The other arm' of'the member or' bar23 is or knee-shaped memberor bar 24 is slidable.

bolted tothe lower surface of the tongue 'or' handle 18 The arm 23- bears against 'the block 1'9. ,A'safety chain 25 may be employ d, as usual,' for supporting the tongue orhandle 18 The brake mechanism may be'readily applied to the, truck, and will not appreciably encumber'the same. When the'tongue or handle 18 is raised, the depending'arm 23 carried bythe tongue '18 -vwill be sprung for-V wardly and upwardly, and will carry the clip or strip 21 therewith. This will swing -wherebythe truck may be readily pulled the brake beam 1 O.forwardly to move the brake shoes away from the" wheels 15, and

or pushed about, As soon as thetongue'l 8 is released, it vwill swing downwardly by gravity, and the depending arm will be swung downwardly and rearwardly and will I push the brake beam 10 rearwardly so that the brake shoes bear against the wheels 15; e

e to exert a braking action thereagainst for preventing the truck from. moving. The

present mechanism therefore operates'auto matically coloring the brake shoes into and V out of frictional engagement with the wheels I when the tongue is. lowered and raised, whereby a person 1n grasplng' the tongue and raisingthe same slightly may readily trundle the truck about, but as :soon as the tongue is released,the brake mechanism will be immediately applied'to prevent further movementof the truck; I The advantages of this appliance will be obviousfromtheforegoing,'taken in connection with theidrawing- T It will be noted that the'tongue' 18- pro- 'jects forwardly considerably frombthel armi 23, whereby the weight of the tongue will exert a considerable rearward-*pressure against the brake beam when the tongue-is.
